Supporrting Members for Dyeing Machines,

of which the following is a specification.

This invention relates to improvements in dyeing, machines, and more especially to dyeing machines of the type in which there is provided a rotatable carrier, in which are supported sticks on which the yarn is held in skeined form, the carrier being rotated so as' to bring the yarn below'the surface of the dye liquor with which the yarn is to be dyed. In yarn dyeing machines :of' this character,

the carrier'is customarily provided with an inner and an outer series of yarn sticks which extend between portions of the carrier, the yarn skeins being supported oncorresponding sticks of the inner and outer ser es. Inasmuch as the portion ofthe ske'ins in engagement with the dye sticks are prevented from being thoroughly impregnated with the dye l quor, it is necessary to move the skeins. relatively to said dye sticks so that the dye liquor will, be permitted to equally impregnate all portions of the flanges 2, suitably bored so as to provide a bearing for the yarn stick supporting memskeined yarn.

To accomplish this end the sticks are mounted at one end in a stick supporting member which is rotatably mounted in the rim portionof the carrier, the stick supporting member being provided with a star Wheel which engages the trip as, the carrier is rotated, the trip. causing the stick supporting member to be tur'nedby one tooth so that the yarn skeins are moved by degrees about the two sticks. Means is also provided on the stick supporting members to prevent a retrograde movement;

Inasmuch as the stick supporting members ar'eimost conveniently used when made so as to be removable from therimmed portion of the carrier, is necessary to provide somecheap and eiiicient'means by which the 'members may beheld against withdrawal from the rim portion ofthe carrier. One object of this invention is to provide aneflicient and, simple means to secure the yarn stick supporting members in the rim portion of the carrier.

Another object is to provide a means for securing the stick supporting members in the rim portion of the carrier, which may beyond.

be readily operated, and which is positive in itsaction to keep the members from being accidently displaced therefrom.

- Other objects and aims of the invention, more or less specific than those referred to above, 'will be in part obvious and in part pointed out in the course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting the invention; and thescope of protection contemplated will be indicated in the appended claims.

In the accompanying drawing, wherein we have shown a preferred form of embodiment of our invention: 7

Figure 1 is a cross-sectional view of the rim portion of the carrier, showing the yarn stick supporting member in side elevation. Figure 2 is an end view similar to Figure Figure 3 is a detail view of the securing means.

With reference now to the drawing, where in similar reference characters refer to similar parts throughout the views thereof, the referencecharacter 1 designates the rim portion of a carrier which is made of cast metal of some kind. At suitable intervals in the aortion 1 there are provided extending her. The latter member consists of a shank 3, upon one end of which is mounted a star wheel 4, the star wheel being provided with a hub a at the point where it joins the shank, the hub 41? being of'such diameter as to overlie the end face of the bearing 2; The

shank 3 projects through the bearing in the flange 2 and extends a short distance there- Formed on the end of the shank 3 is a ratchet wheel 5, the ratchet wheel being of less diameter than the shank. Mounted on the rim portion of the carrier is a springfinger or pawl 6, mounted on the carrier rigidly in any desired way, so as to engage the teeth of the ratchet wheel to prevent retrograde movement ofthe carrier.

The pawl '6 is provided with a finger 7, struck up therefrom, the finger 7 being of such form that it may be readily engaged, so that the spring finger or pawl 6 may be dis engaged from the teeth of the ratchet should occasion demand.

In the surface of the shank 3 there is cut a peripheral channel 8, this channel being semi-circular in cross-section, and being adapted to have a spring-ring 9 held therein, the channel 8 being so positioned relatively to the inner face of the rim portion of the carrier that when the spring ring is in position therein, the shank will be prevented from movement so as to withdraw the supporting member from the bearing.

As illustrated in Figure 2, there is provided a trip 10 mounted in any convenient manner relative to the carrier, so that as the rim portion 1 revolves, as indicated by the arrow thereon, the trip 10 will project into the path of one of the teeth 11 on the star wheel, moving that tooth in the direction indicated by the arrow corresponding thereto. In the face of the star wheel 4t thereis provided a suitable mounting for the yarn stick, this feature not being shown, the yarn stick, however, entering into a suitable bore in the face of the star wheel so that as the star wheel is rotated the yarn stick will rotate therewith. In order to mount the yarn stick supporting member in position on the rim, the shank 3 is inserted into the bearing, and moved until the hub r is in contact with the outer face of the bearing, as indicated in Figure 1. The spring-finger of pawl 6 is then raised out of engagement of the teeth of the ratchet, and the springring 9 forced over the surface of the shank until it slips into position in the channel 8,

where it will be held by its own resiliency. ,The spring-finger or pawl 6 is then permitted to spring back into position in engagement with the teeth of the ratchet.

It will be seen that the yarn stick supporting member of the form shown may be mounted in position on the carrier with the star wheel either on the inner or outer faces of the carrier, it being only necessary to reverse'the position of the shank in the bearing 2, and also to mount the pawl 6 in any convenient manner on the other end face of the bearing 2.

It will accordingly be seen that we have provided a yarn stick supporting means provided with a locking device thereon, which is well adapted to attain all the objects, and perform all the functions set forth. The device is easily operable and forms a positive lock. It is economical in use, all the parts being cheaply made.

As many changes could be made in this .construction withoutdeparting from the scope of the following claims, it is intended that all matter contained in the above description .or shown in the accompanying drawing shall be interpreted as illustrative only and not in a limiting sense.

aving thus described our invention what we claim as new and desire to secure by Letters Patent is:

1. In apparatus of theclass described, a

2'. In apparatus of the class rotary carrier provided with an outerrim portion, said rim portion being provided with a bearing, a stick supporting member having a shank rotatably mounted inv-said bearing andprojecting beyond either end thereof, a star wheel on one end of said shank, a ratchet wheel formed integrally on the other end of said shank, said wheelbedescribed, a

ing ofless diameter than thesaid bearing,

a pawl on said rim portion to engage said ratchet wheel, and means onthe projecting portion of said shank adj acent'said ratchet wheel to prevent the removal of said shank from said bearing. I v v j 3.

4. In apparatus of the class described, a rotary carrier provided with an outer rim portion, said rim portion being provided with a bearing, a stick supporting member having a shank rotatably mounted in said bearing and projecting beyond one end thereof, a hub on one end of said shank overlying the end face of said bearing, a star wheel on said hub, a ratchet wheel on the projecting end of said shank, said ratchet wheel being of less diameter than said shank, a pawl mounted on said rim por tion to engage said ratchet wheel, a channel cut peripherally in the projecting end of said shank, and a ring adapted to be mounted in said channel so as to engage, said rim portion whereby to prevent the withdrawal of said shank from said bearing. j

5. In apparatus of the class described, a
